Calcine oyster-shells, pound them, sift them through a silk sieve, and
grind them on porphyry till they are reduced to the finest powder.
Then take the whites of several eggs, according to the quantity of the
powder; and having mixed them with the powder, form the whole into a
kind of paste. With this paste join the pieces of china, or glass, and
press them together for seven or eight minutes. This cement will stand
both heat and water, and will never give way, even if the article
should, by accident, fall to the ground.
